Ok guys, If you want the quick and dirty of the results jump down to the results and pics.
Otherwise here is what I did. I shot 3 shots each of unsorted,
JSB 25.39gr
AirArms Diabolo Field 25.4gr
JSB Exact King Heavy MKII 33.95gr
Benjamin 6.4mm head but without posted weights. on can.
All target measurements are in inches. Measured outer edge to outer edge, not center to center.
Range conditions: 30yds, winds East 10mph, Humidity 80% (normal conditions are usually southern winds but we are about to get hit by Hurricane Harvey here in Texas)
Shooting: FX Streamline .25 no adjustments. shooting from a one piece portable bench, heart beat visible in scope. Front and rear bag rests. Single shot tray used.
Scope: Hawke 8.5-25x42 tactical, set at 24 power. Anti cant bubble used.
Procedure: I filled the gun to 225bar prior to each new pellet mfg. I then shot 3 warm up shots which are shown with circles around them. I then shot multiple groups of 3 shots at each bull so that I could get a better average or better dispersion of data.
First up was the JSB 25.39.
This pic is the very first three shots for the warm up. Notice there is not much need to worry about the reg setting in as I have mentioned on other threads. This gun shoots pretty well after a fill with little to no POI change with fresh air fills to 230bar, 225bar for this test.
Take note that this was a warm up 3 shot round, was not suppose to count in the story, actually I didn't plan on even showing these, but as it turns out I must be a little shy about performance....because this was the best group of the day. .258 for three shots. JSB 25.39g
I then shot the "competitive" groups for the JSB 25.39 and they are shown in this pic.
I shot 4 different groups. Groups range from .340 to .523 for the JSB 25.39
The next pellet up was the JSB 33.95g. Heavy MKII. Here is the practice pic.
My POA is for the #6 bull and the #27 bull. The groups were 1.18 and 0.919 respectively. These were shooting so sporadic I didn't feel comfortable shooting them in the competition part of the target, for fear of hitting out of the respective grouping and ruining the bulls outside the designated area. So these are the only shot I took with the Heavies. I have shot these before with the Streamline, in the chrony thread I started a few days ago and they grouped much better, still not as good as the 25.39's. I don't know if it is because the wind is out of the east today and normal prevailing winds are out of the south? I just don't know at this point.
So the next pellet up is the AirArms Diabolo Field at 25.4g(AA). Here is the practice group.
Very respectable grouping here at .414 for the practice. Keep in mind these were shot just after shooting the JSB Heavies and with a fresh fill to the gun at 225Bar. This gun is so sweet to stay on POA after a fill, it just makes me giddy. lol. Sorry, I digress. Here are the competition shots for the AA pellets.
The AA column is bulls 12, 24, 35, 38, and "43" for fun. Basically the center column of the 3 column shown in full. The results ranged from 0.301 to 1.098. The 1.098 group had one flyer that hit just above the 23 bull over in the JSB HVY column. I really think that was on me, I noticed I had the gun somewhat "pre-loaded" between the bags after the shot. It is what it is, so I included it since I was shooting in the "competition" area. Still not a bad grouping string for the AA pellets. The reason I said "43" for fun was because it was hidden in the grass. I could just make out the top of the "3" in 43 and had to extrapolate where the bull was in the grass. Hence why the green stain. lol.
Next up we have the Benjamin pellets. Again the gun is filled to 250bar before the shots are taken. Here is the practice pic.
First shot was in the bulls! I was excited! And I think it probably shows, since the next two shots were well grouped together but were down and left slightly. Yielding a 0.505 practice group. Not bad Benji, lets see how you do in competition. Here is the comp pic. for the Benj.
I only shot two groups with the Benj in the competition part of the target. Simply because that was a total of three groups all less than the .505 from practice. The competition shots came in at .356 to .379. About the best I could expect from these pellets so I stopped there.
SUMMARY:
JSB 25.39 groups range from .258 to .523
JSB Hvy MKII groups range from .919 to 1.18
AirArms 25.4g groups range from .301 to 1.098 (.698) if we delete the flyer, due to me.
Benjamin groups range from .356 to .505
How I would rank as the favorite pellet of the Streamline would be JSB 25.39, then the AirArms, then the Benjamin, then the JSB Hvy MKII.
If you like what I did and got something out of it please feel free to pass along a few comments and some accuracy points. I look forward to seeing how other streamlines compare and what you guys think your guns favorite pellet is. Thanks so much for your time. I really do like this streamline. Thanks FX.
